On January 06, 2021, we released an update (Version 1.5: 06 January 2021) of the installation routines as well as the toolbox.

For the Windows installation routines, we updated gnuplot, geany and cygwin to their latest stable versions.

Apple released its next major update of the macOS operating system. When you have upgraded your Mac to macOS Big Sur, you might experience problems with running gfortran on your system. To solve such problems, you will have to completely uninstall and re-install all necessary software. We recommend to proceed as follows:

• Download the new installation routines for macOS from our website and execute uninstall_fortran.command to remove all relevant software.
• Next, reinstall the XCode developer tools. Open a terminal and type
  
sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install

  You will be prompted to confirm the reinstallation of the developer tools. Wait for this installation to complete.
• Next, reinstall Fortran by running install_fortran.command

We also released a small update of the toolbox, which corrects some errors with the calculation of log-normal distributions.
